Taher- physics- Projectile motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What is the direction of the acceleration for any projectile?

Back

Down, due to the force of gravity.

Front

What remains constant in horizontal projectile motion?

Back

The horizontal speed remains constant if air resistance is ignored.

Front

What is the formula for calculating the time of flight for a projectile?

Back

Time of flight = (2 * initial velocity * sin(θ)) / g, where θ is the launch angle and g is the acceleration due to gravity.

Front

What is the maximum height of a projectile?

Back

The maximum height is reached when the vertical component of the velocity becomes zero.

Front

How do you calculate the range of a projectile?

Back

Range = (initial velocity^2 * sin(2θ)) / g, where θ is the launch angle.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance reduces the range and maximum height of the projectile.

Front

If a stone is thrown vertically upwards with a velocity of 8 m/s, how long does it take to reach maximum height?

Back

0.8 seconds.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s² near the surface of the Earth.

Front

How fast is an object falling after 2 seconds?

Back

After 2 seconds, an object in free fall will be moving at approximately 19.6 m/s.
